FIELD OF THE INVENTION

The present invention relates to compositions to treat wood. More particularly, the present invention relates to compositions and methods for treating wood to control insects and more particularly, kill termites, while deterring and preventing termite infestations.

DESCRIPTION OF THE RELATED ART

A pest is an organism which is detrimental to humans or human concerns. Pests include insects, plant pathogens, weeds, molluscs, birds, mammals, fish, nematodes (round-worms) and microbes.

Typically, pests are classified into insects, mites, nema-todes and gastropods. Pesticides are substances or mixture of substances intended for preventing, destroying, repelling or mitigating any pest. A pesticide may be a chemical agent, a biological agent (such as a virus or bacterium), an anti-microbial, a disinfectant or a device used against any pest.

Pesticides are categorized into four main substituent chemicals: herbicides, fungicides, insecticides and bacteri-cides. Pesticides can be classified by target organism, chemical structure and physical state. Pesticides can also be classed as inorganic, synthetic, or biological (bio-pesticide). Bio-pesticides include microbial pesticides and biochemical pesticides. These include pyrethroids, rotenoids and nicoti-noids. Pesticides can also be classified based upon their biological mechanism function or application method. Most pesticides work by poisoning the pests.

An insecticide is a pesticide used against insects. They include ovicides and larvicides, used against the eggs and larvae of insects respectively. Insecticides are classified in several different ways. Typically, they are classified as systemic insecticides, contact insecticides, natural insecti-cides, plant-incorporated protectants (PIPS), inorganic insecticides and organic insecticides. The commonly known insecticides include: i) organochlorides such as DDT, aldrin, chlordane, chlordecone, heptachlor, methoxychlor, pen-tachlorophenol and the like; ii) organophosphates such as acephate, azinphos-methyl, bensulide, chlorethoxyfos, chlo-rpyrifos, diazinon, dimethoate, disulfoton, ethoprop, fenamiphos, parathion, trichlorfon and the like; iii) pyrethroids such as allethrin, bifenthrin, cyhalothrin, lambda-cyhalothrin, cypermethrin, cyfluthrin, prallethrin, transflu-thrin and the like, iv) carbamates such as aldicarb, bendiocarb, carbofuran, carbaryl, dioxacarb, fenobucarb, fenoxycarb, isoprocarb, methomyl and the like.

Commercially available insecticides, including those available for home use, commonly comprise active ingredients or poisons which are not only toxic to the target insect pests, but, if used in relatively confined environments and delivered as aerosol sprays, can be present in sufficient concentration to also be toxic to humans and household pets. Various undesirable side effects may include immediate or delayed neurotoxic reactions, and/or suffocation. Even the noxious odor of such materials can cause headaches or upset stomachs in some individuals. These adverse side effects are exacerbated when such compositions come in contact with persons of increased sensitivity, or persons of small body mass such as children or babies.

For some time, efforts have been made to develop insecticidal compositions, particularly those intended for residential use, which are effective in killing the targeted insect pests completely and quickly, but non-toxic to humans and pets. The Environmental Protection Agency (EPA) regulates the use of potentially toxic ingre-dients in pesticidal compositions under the Federal Insecti-cide, Fungicide and Rodenticide Act (FIFRA). Certain mate-rials considered to be either active or inert materials by the EPA have been deregulated or otherwise identified as accept-able safe substances under FIFRA offering minimum risk in normal use. Other materials are currently undergoing inves-tigation and may be deregulated in due course. Consumers generally consider deregulated substances non-poisonous or non-toxic. Thus, the term non-toxic or non-poisonous as used herein is intended to convey a compound or composition that, while highly effective in killing targeted insect pests, is safe to use around humans, particularly small children, and pets.

The search for a new repellent or termiticide is difficult because studies have shown that termites show unexpected sensitivity to chemicals, sensitivity that differs from that of other insects. For example, phenoxyethanol has been shown to be a trail-following substance; and naphthalene, a toxicant for most insects, was found to be used as fumigant by termites for their nests at concentrations that would kill fire ants, as disclosed in U.S. Pat. No. 5,874,097. That and other conventional compositions are disclosed in the following U.S. Patents and U.S. Pat.ent Application Publications, which are incorporated herein by reference:

While such conventional compositions and methods may be partly suitable for the particular purpose employed, they would not be as suitable for the purposes of the present invention as disclosed herein.

DETAILED DESCRIPTION

For a further understanding of the nature and function of the embodiments, reference should be made to the following detailed description. Detailed descriptions of the embodiments are provided herein, as well as, the best mode of carrying out and employing the present invention. It will be readily appreciated that the embodiments are well adapted to carry out and obtain the ends and features mentioned as well as those inherent herein. It is to be understood, however, that the present invention may be embodied in various forms. Therefore, persons of ordinary skill in the art will realize that the following disclosure is illustrative only and not in any way limiting, as the specific details disclosed herein provide a basis for the claims and a representative basis for teaching to employ the present invention in virtually any appropriately detailed system, structure or manner. It should be understood that the devices, materials, methods, procedures, and techniques described herein are presently representative of various embodiments. Other embodiments of the disclosure will readily suggest themselves to such skilled persons having the benefit of this disclosure.

The advantages and significant benefits of the present invention include high solids, more film build, better flow, higher luster, when compared to conventional lacquers in performance without the toxicity. The present invention can be safely used by chemically sensitive users and has a mild odor content similar to citrus scent. The present invention fights indoor air pollution by sealing in off gassing and containing a very low volatile organic compound (VOC) content, which meets or exceeds all federal and state air quality regulations, including California’s. Unlike many commercially available products the composition of the present invention contains no formaldehyde. The evaporation rate of the compositions of the present invention are slower than ether and have a vapor density that is heavier than air.

Therefore, in accordance with preferred embodiments of the invention there are provided insect repelling compositions of non-toxic wood preservatives that can be applied directly to the wood of a home’s interior or exterior that are safe for pets and humans. The insect repelling compositions are able to deter, kill, and/or prevent insects from accessing wood which may serve as a food source for insects that come into contact with these compositions. According to inventors’ research, the termite species termites subterranean excretes an alarm pheromone when exposed to a compound sourced from citrus fruit peels known as D-Limonene (C₁₀H₁₆). The d-isomer of limonene, a monoterpene and cycloalkene, occurs commonly in nature as the fragrance of oranges. The alarm pheromone excretion of termites is a natural defense mechanism of termites subterranean. Accordingly, when subterranean soldier termites detect danger in a location, these termites excrete the alarm pheromone to warn other termites of the danger, thereby, directing the other termites to avoid that location. When wood is treated with D-Limonene, the compound creates a zone of danger or discomfort perceived by wood boring insects, signifying to these insects that the zone is not inherently safe. The compositions of the present invention are believed to have long lasting effects, which deter and/or kill insects that come into contact with it, affecting a wide range of wood boring and eating insects, including termites, carpenter ants, and carpenter bees. The compositions of the present invention cause termite death, which result from destruction of the digestive and respiratory systems of termites. These compositions of the present invention are effective for many years and also assist with sealing outgassing.

Therefore, in accordance with embodiments of the invention there is provided a non-toxic insect control composition for treatment of a wood surface in interior and exterior settings. The composition of the present invention is preferably a clear, hard and durable, water-based acrylic compound. The composition includes D-Limonene, in a range of at least 5% to approximately 30% by weight, a non-toxic emulsifying agent, in a range of at least 1% to approximately 20% by weight, water in a range of at least 20% by weight to approximately 60% by weight of water, a modified acrylic emulsion copolymer in a range of at least 20% by weight to approximately 45% by weight, dipropylene glycol methyl ether in a range of at least 1% by weight to approximately 10% by weight, Polysiloxane Polymer in a range of at least 1% by weight to approximately 5% by weight, and an Amine solution in a range of at least 1% by weight to approximately 5% by weight. The D-Limonene can be derived from a variety of citrus fruits and other plants and is commercially available under the name Cold Pressed Orange Oil, for example.

Example 1 Objective

To demonstrate the effectiveness of a termicidal composition in accordance with embodiments disclosed herein, an experiment was conducted to evaluate treated cellulose material for its resistance to subterranean termites the American Wood Protection Association (AWPA) Standard E1-13 was implemented. In the experiment, single choice tests and two choice tests were performed simultaneously. The experiment tested wood treated with one embodiment of the claimed invention against Formosan subterranean termites, Coptotermes formosanus, as the targeted insect. The experiment was conducted utilizing the embodiment of the invention containing the insect repelling composition which includes approximately 25% by weight cold pressed orange oil component having a D-Limonene concentration of at least 80%, and approximately 75% by weight acrylic lacquer component, with the acrylic lacquer component comprising approximately 45% by weight modified acrylic emulsion copolymer, at least 40% by weight water, at least 5% by weight dipropylene glycol methyl ether, at least less than 5% by weight polysiloxane polymer, and at least less than 5% by weight amine solution. Five replications were made for each of the following treatments:

-   Treatment 1: Single choice test-Untreated controls. -   Treatment 2: Single choice test-Wood blocks with one (1) coat of     treatment applied. -   Treatment 3: Single choice test-Wood block with two (2) coats of     treatment applied. -   Treatment 4: Two choice test-Control and wood blocks with two (2)     coats of treatment applied. -   Treatment 5: No wood blocks-Termites only to evaluate the overall     health of the termites.

Methods

The wood specimens to be tested are allowed to air dry for one week and are then weighed. Sterilized glass jars are filled with 150 g of sand and 30 ml of distilled water. The sterilized glass jars are allowed to stand for two hours. For the single choice tests, a solitary test block is placed on the sand surface. For the two choice test, two different types of wood blocks, a treated wood block and a control wood block, are placed on opposite sides of the jar. A piece of aluminum foil is placed under each treated wood block to prevent leaching of the embodiment of the present invention into the sand.

Termites were collected from the field from the West End neighborhood in the city of New Orleans, Louisiana. The average weight of the collected termites were measured, as illustrated in Table 1 below. Four hundred termites, consisting of 380 worker termites and 20 soldier termites, were placed inside each test jar. These jars were maintained at 28° C. and 80% relative humidity (RH) for four weeks.

Each jar is weighed weekly to ensure moisture level is maintained. At the end of the four weeks, test jars are disassembled.

Each block is removed, cleaned with a brush, and allowed to air dry before weighing, as shown in Table 2 below.

The number of live termite workers and soldiers are determined for each test jar, as shown in Table 3 below.

Each test block was visually rated using the rating system defined in the AWPA E1 Standard below:

AWPA E1 Standard Visual Rating System of Each Test Block Grade # Description of Condition Cross Section Affected (%) 10 Sound (No Biological Deterioration) N/A 9.5 Trace surface nibbles N/A 9 Slight attack ≤ 3 8 Moderate attack 3-10 7 Moderate/severe attack, penetration 10-30 6 Severe attack 30-50 4 Very severe attack 50-75 0 Failure

The single choice wood blocks treated with one coat of the composition resulted in termites only consuming on average 10.164% of the wood blocks and killed approximately 36.75% of the termites. In comparison, the single choice untreated, control wood blocks resulted in termites consuming 30.114% of the wood blocks and only 11.95% of the termites died. Under the two choice test, approximately 25.15% of the termites died and while the termites consumed on average 21.392% of the untreated, control wood blocks, only 2.852% of the two coat treated wood blocks were consumed.

Example 2 Objective

To further evaluate the effectiveness of termiticidal compositions disclosed herein in accordance with embodiments of the invention, an additional experiment was conducted to evaluate treated cellulose material for its resistance to subterranean termites and to compare conventional termiticide to the compositions, in accordance with embodiments of the invention. The American Wood Protection Association (AWPA) Standard E1-13 was implemented. In the experiment, single choice tests and two choice tests were performed simultaneously. The experiment tested wood samples treated with four different compositions, of which three of the compositions were provided in accordance with embodiments of the invention disclosed herein, and the fourth composition was the conventional BORA-CARE® termiticide composition produced by Nisus Corporation. The tested wood samples were treated with a Treatment Y, a Treatment X, a Treatment B, and a Treatment BC, for use against Formosan subterranean termites, Coptotermes formosanus, as the targeted insect.

The experiment was conducted utilizing the following treatments:

Treatment Y includes soaking the wood block in pure cold pressed orange oil, containing at least 80% D-Limonene, until the wood is completely saturated, then allowing the wood to dry and then coating the wood with a composition, in accordance with embodiments of the present invention. The composition included approximately 25% by weight cold pressed orange oil component having a D-Limonene concentration of at least 80%, and approximately 75% by weight acrylic lacquer component, with the acrylic lacquer component comprising approximately 45% by weight modified acrylic emulsion copolymer, at least 40% by weight water, at least 5% by weight dipropylene glycol methyl ether, at least less than 5% by weight polysiloxane polymer, and at least less than 5% by weight amine solution.

Treatment X, includes coating the wood with a composition, in accordance with embodiments of the present invention, which includes approximately 25% by weight cold pressed orange oil component having a D-Limonene concentration of at least 95%, and approximately 75% by weight acrylic lacquer component, with the acrylic lacquer component comprising approximately 45% by weight modified acrylic emulsion copolymer, at least 40% by weight water, at least 5% by weight dipropylene glycol methyl ether, at least less than 5% by weight polysiloxane polymer, and at least less than 5% by weight amine solution.

Treatment B, includes coating the wood with a mixture of Treatment X and approximately 25%, by weight pure boric acid (in power form).

Treatment BC, includes coating the wood with the conventional termiticide BORA-CARE®.

Five replications were made for each of the following treatments:

Treatment 1: Single choice test-Untreated controls.

Treatment 2: Single choice test-Wood blocks with Treatment Y applied.

Treatment 3: Single choice test-Wood block with Treatment B applied.

Treatment 4: Single choice test-Wood block with Treatment BC applied.

Treatment 5: Single choice test-Wood block with Treatment X applied.

Treatment 6: Two choice test-Wood block with Treatment BC applied and Wood block with Treatment X applied.

Treatment 7: No wood blocks-Termites only to evaluate the overall health of the termites.

Methods

The wood specimens to be tested are allowed to air dry for at least one week and are then weighed. Sterilized glass jars are filled with 150 g of sand and 30 ml of distilled water. The sterilized glass jars are allowed to stand for two hours. For the single choice tests, a solitary test block is placed on the sand surface. For the two choice test, two different types of wood blocks, a wood block treated with Treatment BC and a wood block treated with Treatment X, are placed on opposite sides of the jar. A piece of aluminum foil is placed under each treated wood block to prevent leaching of the embodiments of the present invention into the sand.

Termites were collected from the field from the Elysian neighborhood in the city of New Orleans, Louisiana. The average weight of the collected termites were measured, as illustrated in Table 1 below . Four hundred termites, consisting of 360 worker termites and 40 soldier termites, were placed inside each test jar. These jars were maintained at 28° C. and 80% relative humidity (RH) for four weeks.

For the single choice tests, the average weight consumed of the control, untreated, wood was 0.835 g, while that of the wood treated with Treatment Y of the composition was 0.309 g, the wood treated with Treatment B of the composition was 0.200 g, the wood treated with Treatment BC of the composition was 1.496 g, and the wood treated with Treatment X of the composition was 0.356 g. Testing revealed that there was a statistically significant difference in the amount of untreated wood consumed and the amount of treated wood consumed (P < 0.001).

Analysis of variance (ANOVA) was performed following a Tukey Test to rank treatments for the Single choice tests, as illustrated in Table 3 below, which utilized pairwise multiple comparisons between treatments. The treatments tested in this experiment which are ranked with the same letter showed no significant differences in termite mortality.

FIG. 5 illustrates a photograph of the control, untreated wood block samples after the experiment, wherein the termites consumed on average 51.24% of the wood blocks, by weight. As seen in FIG. 6 , which illustrates a photograph of the wood samples treated with Treatment Y, in accordance with embodiments of the invention, after the experiment, wherein the termites only consumed on average 4.762% of the wood blocks, by weight. As seen in FIG. 7 , which illustrates a photograph of the wood samples treated with Treatment B, in accordance with embodiments of the invention, after the experiment, wherein the termites only consumed on average 3.754% of the wood blocks, by weight. As seen in FIG. 8 , which illustrates a photograph of the wood samples treated with Treatment BC after the experiment, wherein the termites consumed on average 21.916% of the wood blocks, by weight. As seen in FIG. 9 , which illustrates a photograph of the wood samples treated with Treatment X, in accordance with embodiments of the invention, after the experiment, wherein the termites only consumed on average 6.312% of the wood blocks, by weight.

As seen in FIG. 10 , which illustrates a photograph of the two choice tests, comparing wood block samples treated with Treatment BC and wood block samples treated with Treatment X, in accordance with embodiments of the invention, after the experiment. Therefore, the experiment revealed that for the two choice tests, there was a significant difference between wood consumption (t = 2.612, df = 2, P = 0.031). Termites consumed significantly more wood treated with Treatment BC than wood treated with Treatment X.

As seen in Table 3 above, the effectiveness of Treatment BC (consisting of the conventional termiticide BORA-CARE®) at repelling termites and preventing said termites from consuming the wood blocks is significantly less effective than treatments utilizing embodiments of the present invention.

This experiment indicated that the compositions of the present invention are effective at repelling and killing termites from treated wood samples. The compositions, in accordance with embodiments of the present invention, are significantly more effective at repelling termites and nearly or just as effective at killing termites as compared to conventional termiticides.

As seen in the data set forth in Example 1 and Example 2 above, the embodiments of the present invention identified herein offer a safe and effective method for controlling termite infestations. Further, the treatment processes described herein provide effective use as termite repellents, termiticides, and wood preservatives. The treatment processes may also be used with effectiveness for protection from other wood boring insects.

To the extent there may be perceived health or environmental concerns with existing termite repellents, termiticides, and wood preservatives, the ability to replace or reduce the amount of toxic termiticides and toxic wood preservatives by use of the present invention offers additional benefits as well. The non-toxic nature of the present invention makes embodiments of the invention ideal candidates for preventing, and treating termite infestations in both household and commercial settings.

The compositions of the present invention can be utilized on wooden surfaces, preferably unfinished or properly prepared and sanded previously finished wooden surfaces. All surfaces should preferably be clean and free from dirt, dust, grease, wax oil, silicone, tsp/soap, mill scale, oxidation, loose peeling paint or varnish, or any foreign matter/contaminants. The compositions of the present invention should be applied where there is adequate ventilation.

The compositions of the present invention may cause mild irritation to the eyes, skin, and respiratory tract. Therefore, users are advised to use the correct personal protective equipment (PPE) when handling the compositions of the present invention.

Referring to the following methods, after wood is treated with one or more of the compositions disclosed herein in accordance with embodiments of the invention, the treated wood is preferably dried in an arid environment with little to no humidity. One skilled in the art can appreciate that increased levels of humidity would cause an increase in the amount of time required for the treated wood to completely dry.

In accordance with embodiments of the invention, there is provided a preferred method of treating wood for use in interior and exterior settings with an insect repelling composition. In such embodiment, before applying the insect repelling composition to wood, a user should mix the composition thoroughly, preferably by gently stirring the composition, or by rolling a container housing said composition, in an effort to avoid air bubbles. Preferably, the composition should be stirred thoroughly for approximately 20 minutes prior to application. The preferred method comprises applying the insect control composition to at least one wood surface of a piece of wood by painting the composition onto the at least one wood surface, for example, with a quality nylon brush or pad applicator. In such preferred embodiment, the user uses the brush or pad to apply liberal coats of the composition to the at least one wood surface, while avoiding over brushing and keeping the brush or pad saturated with the composition. Preferably, the user applies a first coat of the composition to the at least one wood surface to a point of surface saturation. Then, the method preferably includes waiting approximately 6-24 hours to allow the composition of the first coat to completely dry. Once the composition applied to the at least one wood surface is substantially or completely dry, the user applies a second coat of the composition to the at least one wood surface to a point of surface saturation. The method further includes waiting an additional approximately 6-24 hours to allow the composition of the second coat to completely dry.

In one embodiment, the user adds water the composition to achieve desired consistency before applying the first coat.

In another preferred embodiment, there is provided a method of treating a piece of lumber with a wood preserving insect repelling composition. In one embodiment, for example, a preferred wood preserving insect repelling composition comprises 25% cold pressed orange oil having a D-Limonene concentration of at least 80% (and more preferably of at least 90%, and most preferably of at least 95%) and 75% acrylic lacquer. In a preferred embodiment, the acrylic lacquer comprises approximately 45% by weight modified acrylic emulsion copolymer, at least 40% by weight water, at least 5% by weight dipropylene glycol methyl ether, at least less than 5% by weight polysiloxane polymer, and at least less than 5% by weight amine solution, The method includes a step of first dipping the piece of lumber into cold pressed orange oil having a D-Limonene concentration of at least 80% and preferably leaving the piece of lumber in the cold pressed orange oil for at least 24 hours, until the piece of lumber is completely saturated with the cold pressed orange oil. The preferred method then includes a preferred step of placing the piece of lumber in a dryer to dry out the piece of lumber. Once the piece of lumber is substantially or completely dried out, the method preferably includes a step of applying a first coat of the wood preserving insect repelling composition to at least one surface of the piece of lumber to a point of surface saturation by painting said at least one surface with a brush or pad, applying liberal coats of the composition to the at least one surface, while avoiding over brushing and keeping the brush or pad saturated with the composition. Preferably, the piece of lumber is completely dry prior to the step of applying the first coat of the composition to treat the piece of lumber. In such manner, it is believed that allowing the piece of lumber to completely dry prior to the application of the composition provides improved penetration of the composition into cells of the piece of lumber. Post preferably, the piece of lumber saturated with the cold pressed orange oil is allowed to dry in a non-humid environment.

In one embodiment, the method includes a step of waiting until the first coat is completely dry before applying a second coat of the composition. The method further includes a step of applying the second coat of the wood preserving insect repelling composition to the at least one surface of the piece of lumber to a point of surface saturation by painting the at least one surface with the brush or pad, applying liberal coats of the composition to the at least one surface, while avoiding over brushing and keeping the brush or pad saturated with the composition.

In another embodiment, the method further includes a step of waiting until the second coat is completely dry before handling the treated wood.

In yet another embodiment, the wood preserving insect repelling composition includes at least 75% commercial wood preservative and at least 25% cold pressed orange oil having a D-Limonene concentration of at least 80% (and more preferably of at least 90%, and most preferably of at least 95%), to cause said composition to bond properly to the at least one surface of the piece of lumber and to keep in the scent of the D-Limonene active for an extended period of time.

In another embodiment, the user can add water the composition to achieve desired consistency before applying the first coat.

In another preferred embodiment, there is provided a method of treating wood for use in interior and exterior settings with an insect repelling composition. In such embodiment, before applying the insect repelling composition to wood, a user should mix the composition thoroughly, preferably by gently stirring the composition, or by rolling a container housing said composition, in an effort to avoid air bubbles. Preferably, the composition should be stirred thoroughly for approximately 20 minutes prior to application. The preferred method comprises applying said insect control composition to at least one wood surface by spraying the composition onto said wood surface with an unheated spray applicator. The user applies a first coat of the composition to the at least one wood surface to a point of surface saturation. The method includes waiting approximately 6 to 24 hours to allow the composition of the first coat to completely dry. Once the composition applied to the at least one wood surface is completely dry, the user applies a second coat of the composition to the at least one wood surface to a point of surface saturation. The method further includes waiting an additional approximately 6 to 24 hours to allow the composition of the second coat to completely dry.

In yet another preferred embodiment, there is provided a method of pre-treating wood for use in interior and exterior settings with an insect repelling composition. In such preferred embodiment, before pre-treating the wood with the composition, a user should mix the composition thoroughly by gently stirring or rolling a container housing said composition to avoid air bubbles. In such preferred embodiment, the method includes applying a first coat of the insect repelling composition to pretreat a piece of wood by soaking the piece of wood with said insect repelling composition to a point of wood saturation. A user pre-treating the piece of wood removes the piece of wood at the point of wood saturation from the container housing the composition. The method includes allowing the piece of wood at the point of wood saturation with the composition to dry for approximately 8 to 24 hours before handling the piece of wood.

In one embodiment, the method further includes applying a second coat of the insect repelling composition to the piece of wood after the piece of wood at the point of wood saturation with the composition has dried for approximately 8-24 hours by soaking said piece of wood in the composition to the point of wood saturation and allowing the piece of wood to dry for an additional approximately 8 to 24 hours before handling said piece of wood.

In another embodiment, the user can add water the composition to achieve desired consistency before applying the first coat.

In another preferred embodiment, there is provided a method of treating wood with an insect repelling composition for use in interior and exterior settings. The method includes a step of first dipping the piece of wood in cold pressed orange oil, a second step of leaving the piece of wood in the cold pressed orange oil for approximately 24 hours, a third step of letting the piece of wood dry for approximately 24 hours. Once the piece of wood is dry, the method includes a step of applying a first coat of the insect repelling composition to the piece of wood to a point of surface saturation by dipping and soaking the piece of wood with said insect repelling composition. The method preferably includes a step of waiting at least 24 hours until the first coat is completely dry before applying a second coat. The method includes a step of applying the second coat of the insect repelling composition to the at least one wood surface to a point of surface saturation by dipping and soaking the piece of wood with said insect repelling composition and a step of waiting until the second coat is completely dry before handling the treated wood.

In one embodiment, an insect repelling composition disclosed herein includes at least 70% commercial wood preservative and at least 30% cold pressed orange oil having a D-Limonene concentration of at least 80% to cause said composition to bond properly to the piece of wood and to keep in the scent of the D-Limonene.

In another embodiment, the user can add water to the composition to achieve desired consistency before applying the first coat.

Under normal conditions, the compositions of the present invention dry to the touch in at least one hour and are recoatable after approximately 6 to 24 hours. The composition will continue to cure and become harder over time. Normal conditions preferably include a dry surface, access to fresh airflow, moderate humidity, and temperatures around 70° F. Thick application, high humidity, or conditions other than normal will cause these compositions to dry and cure more slowly. It is advisable to avoid freezing temperatures when applying the compositions of the present invention.
